The present invention is formed by that a piezoelectric ceramic transducing sheet (2) is fixed in a pumping cavity formed by a pump body (3) and a pump cover (1), a one-way valve with an external independent member is inserted into the liquid inlet (5) of the pump body (3) and is formed by assembling a valve (8) and a spring (7) in the valve body (6). The present invention has the advantages of high flow quantity, difficult blockage, convenient installation, high rate of finished products, combination property improvement, good uniformity of products, service life extension and use range enlargement, and is suitable for industrial mass production.
Description
(1) technical field
The present invention relates to the superminiature pump, specially refer to a kind of novel miniaturized hydraulic electronic pump.
(2) background technique
In background technique, the general oil hydraulic pump of selling mostly is a mechanical type on the market, volume is big, be difficult for miniaturization, be difficult for installing, patent applicant of the present invention begins to be devoted to study superminiature electronic pump early than the early 1990s, begins to be applied in the artwork as far back as 1997, as water jet water artwork, geomantic omen vehicle humidifier etc.; The inventor has applied for patent " multi-purpose superminiature electronic pump " in calendar year 2001 again, though overcoming and solved oil hydraulic pump, this pump is difficult for reduced volume, be difficult for installing, flow is little, lift is low, problem such as fragile fracture not, but because the microminiaturization of pump makes pump housing bore passages narrow, the one-way valve of intracavitary unit is successively repeatedly in the working procedure, with the speed of per second 50 times open closed, with water or liquid medium inspiration and extrusion, the suspended matter in the medium filters fully and magnetizes because of can not all be filtered guard and magnet steel, time one for a long time and have a small amount of suspended matter to enter pump chamber, absorption and be suspended on around the spring sheet one-way cock, the spring flapper valve is cantilever type, spring sheet one end is fixed in the pump housing with fixed bolt, at work, liquid medium flows rapidly to the liquid outlet direction, and being spring sheet fixed end place, opposite other direction just formed a dead angle, accumulate over a long period and become dirt by a small amount of suspended material accumulation in the medium, hang over the cantilever end of spring valve plate, spring valve plate is got up by pad, work can not normally reset, cause the service behaviour of pump to reduce, can not normally reset because of spring sheet on the other hand, cause the medium that enters pump chamber to be extruded from liquid entering hole by pump again, cause the pressure release phenomenon, the present patent application people's a kind of water inlet check ball valve of development and design again in " multi-purpose superminiature electronic pump " patent application, attempt to change the water inlet direction and increase flow, but the location is not proper, lacks spring.
(3) summary of the invention
The objective of the invention is to develop for many years on the basis of using superminiature electronic pump and former patent application the inventor, develop a kind of novel miniaturized hydraulic electronic pump, overcome and solve in the former technology that superminiature electronic pump easily stops up, easily pressure release under long-term work, cause working stability relatively poor, problems such as the ball valve location is not good enough, guaranteeing on the volume microminiaturization basis, improve the flow and the working efficiency of pump, improve quality and the combination property and the consistency of product of product, prolonged the working life of product, enlarged using scope, industrialized production preferably.
Technical solution of the present invention is as follows:
Miniaturized hydraulic electronic pump, be connected pump cover 1 by having the pump housing 3 of liquid inlet and outlet 5 with 13, assembling piezoelectric constant transducing sheet 2 in its pump chamber, its pump housing 3 liquid entering holes 5 places connect one-way valve and form a whole, it is characterized in that: in one-way valve, valve body 6 is inlayed to peg graft and is fixed on the liquid entering hole 5 at the pump housing 3 centers, places the elastomeric valves 8 that can up and down reciprocatingly open and close in the valve body 6 on the reducing mouth step, assembling spring 7 between elastomeric valves 8 and the liquid entering hole 5, whole one-way valve is the separate piece external.
Technical solution of the present invention also comprises:
Piezoelectric constant transducing sheet 2 is single-layer sheet, promptly is made up of a slice piezoelectric ceramic 16 that is adhesively fixed on a slice substrate 15, and the leakage proof SOI rubber layer 10 that seals the 1-3 millimeters thick is being covered in its front, and the withstand voltage insulating thin layer 11 of polyester fluorine class is being covered at its back side.
Piezoelectric constant transducing sheet 2, add energy sheet 12 by the other piezoelectric ceramic 16 bonding whole composite beds of forming of a slice stack, the electrode of piezoelectric constant transducing sheet 2 and other piezoelectric ceramic 16 is through series, parallel, promptly form whole through series, parallel by the other piezoelectric ceramic 16 that is adhesively fixed on a slice substrate 15, the leakage proof electrically insulating silicone rubber layer 10 that seals the 1-3 millimeters thick is being covered in its front, and the withstand voltage insulating thin layer 11 of polyester fluorine class is being covered at its back side.
The drain pipe 4 of modulation 360 angle fluid directions but liquid outlet 13 ends of the pump housing 3 sides are pegged graft.
On the reducing mouth step seal boss 14 is arranged in the described valve body 6.
Described elastomeric valves 8 is to make with the flexible material of rubber or nylon or engineering plastics.
Advantage of the present invention and effect:
1, owing to having adopted the positive back side all covering the piezoelectric constant transducing sheet 2 of isolation layer or having added energy sheet 12, effectively raises the safe and reliable property of product, use to add the output power that the energy sheet has improved pump; Have that flow is big, lift is high, Safety performance is reliable, the effect of working stability, through test, improved working efficiency more than 10 times than the superminiature electronic pump of the former development of claimant, per minute can be exported the liquid more than 600 milliliters.2, because the feed liquor one-way valve outside pump chamber, is separate piece, and the pump chamber liquid in-out is unobstructed, and non-return effect is obvious, not pressure release, difficult stifled, not fragile.3, overall structure is oversimplified, and dismounting is convenient, not fragile freely, the removable parts part is also convenient, and consistency of product is good, the yield rate height, improve technology capability, not only improved the quality and the combination property of product effectively, and mass industrialized production preferably.4, owing to solved problems such as valve body is difficult for stopping up, not fragile, so improved consistency of product, reliability and stability, also improved working efficiency, enlarged using scope, not only applicable to the supporting of artwork of spraying water, the more important thing is and be applied in aspects such as needing liquid feeding, transfusion, cleaning, fuel feeding, cooling, lubricated, grinding, metering, preparation, drip irrigation, spray in machining equipment, medical apparatus, precision instrumentation, the industrial automation control, application area comprises all technical fields that need micropump also in continuous expansion.
